Objectives The aim of this study was to evaluate the effectiveness of ilioinguinal neurectomy on postoperative pain in the Lichtenstein tension-free hernioplasty of inguinal hernia. Background Chronic pain following tension-free inguinal hernioplasty is a significant clinical problem that can interfere with normal daily activities. Moreover, the condition can sometimes be debilitating, and treatment is often difficult and challenging. Contrary to the previous belief, division of the ilioinguinal nerve prophylactically during mesh repair has been practiced to reduce the incidence and intensity of persistent postoperative pain after hernia repair. Patients and methods Between April 2015 and October 2016, this prospective, randomized, controlled study included 40male patients above 18years of age with unilateral inguinal hernia who were undergoing the Lichtenstein hernia repair. Patients were randomized into two groups–the ilioinguinal neurectomy group and the ilioinguinal nerve preservation group. Twenty patients were included in each group. Patients were followed-up for inguinal postoperative pain at 1 and 6months using a four-point categorical scale. Groin numbness was also assessed at 1 and 6months using a self-administered questionnaire. Results There were no statistically significant differences between the two groups with regard to postoperative pain after 1 and 6months at rest; however, after coughing 10times, walking up three flights of stairs, and cycling for 10min, there were statistically significant differences–postoperative pain in groupA was 5% and in groupB 30%(P<0.05). There were statistically significant differences with regard to postoperative groin numbness after 1month–postoperative numbness in groupA was 15%(P=0.046). However, after 6months, there were no significant differences between the two groups with regard to groin numbness(P=0.156). Conclusion Ilioinguinal neurectomy should be considered a routine surgical step during the Lichtenstein tension-free hernioplasty.
